PROBLEM TO BE SOLVED: To obtain a resin composition for coloration which, even when melt extruded at a high temperature and high speed, hardly ha can give a film pulsation and excellent in smoothness, etc., by compounding a thermoplastic resin, a metal oxide treated with a silane coupling agent, and a compound having a polymerizable carbon-carbon double bond. SOLUTION: This composition comprises a thermoplastic resin preferably being PE, a metal oxide preferably being titanium oxide treated with a silane coupling agent having a polymerizable carbon-carbon double bond, and a compound having a polymerizable carbon-carbon double bond (e.g. butyl methacrylate) and is prepared by kneading the thermoplastic resin, the metal oxide, and the compound at a temperature which is the softening or melting point of the resin or higher but at which the polymerizable carbon-carbon double bond in the compound can not react. A melt extruded film with a stable shape is obtained from the composition. |
